Budget estimate

$2,000,000 – $3,000,000

The solicitation cites an estimated total contract capacity of $3 million. Assuming a typical IDIQ utilization of 60‑70% of the ceiling over the contract’s life, the award value will likely fall between $2 million and $3 million. Factors influencing the final amount include the number of task orders issued, the specific scope of each order, and any optional year extensions exercised.
